A Worldwide Cost-based Design and Optimization of Tilted Bifacial Solar Farms
M. Tahir Patel, M. Ryyan Khan, Xingshu Sun +1
The steady decrease in the levelized cost of solar energy (LCOE) has made it increasingly cost-competitive against fossil fuels. The cost reduction is supported by a combination of…
Electrical Signatures of Corrosion and Solder Bond Failure in c-Si Solar Cells and Modules
Reza Asadpour, Xingshu Sun, Muhammad. Ashraful Alam
Moisture- and temperature-activated corrosion of metal fingers, mechanical stress induced delamination, and failure of solder bonds rank among the leading failure mechanisms of sol…
Ground sculpting to enhance vertical bifacial solar farm output
M. Ryyan Khan, Enas Sakr, Xingshu Sun +2
The prospect of additional energy yield and improved reliability have increased commercial interest in bifacial solar modules. A number of recent publications have quantified the b…
In-Situ Self-Monitoring of Real-Time Photovoltaic Degradation Only Using Maximum Power Point: the Suns-Vmp Method
Xingshu Sun, Raghu Vamsi Krishna Chavali, Muhammad Ashraful Alam
The uncertainties associated with technology- and geography-specific degradation rates make it difficult to calculate the levelized cost of energy (LCOE), and thus the economic via…
Optimization and Performance of Bifacial Solar Modules: A Global Perspective
Xingshu Sun, Mohammad Ryyan Khan, Chris Deline +1
With the rapidly growing interest in bifacial photovoltaics (PV), a worldwide map of their potential performance can help assess and accelerate the global deployment of this emergi…
Vertical Bifacial Solar Farms: Physics, Design, and Global Optimization
M. Ryyan Khan, Amir Hanna, Xingshu Sun +1
There have been sustained interest in bifacial solar cell technology since 1980s, with prospects of 30-50% increase in the output power from a stand-alone single panel. Moreover, a…
An Illumination- and Temperature-Dependent Analytical Model for Copper Indium Gallium Diselenide (CIGS) Solar Cells
Xingshu Sun, Timothy Silverman, Rebekah Garris +2
In this paper, we present a physics-based analytical model for CIGS solar cells that describes the illumination- and temperature-dependent current-voltage (I-V) characteristics and…
An Optics-Based Approach to Thermal Management of Photovoltaics: Selective-Spectral and Radiative Cooling
Xingshu Sun, Timothy J Silverman, Zhiguang Zhou +3
For commercial one-sun solar modules, up to 80% of the incoming sunlight may be dissipated as heat, potentially raising the temperature 20 C - 30 C higher than the ambient. In the…
Some Useful Relations for Analyzing Nanoscale MOSFETs Operating in the Linear Region
Mark Lundstrom, Xingshu Sun
Several equations used to model and characterize the linear region IV characteristics of nanoscale field-effect transistors are derived. The meaning of carrier mobility at the nano…
A Physics-based Analytical Model for Perovskite Solar Cells
Xingshu Sun, Reza Asadpour, Wanyi Nie +2
Perovskites are promising next-generation absorber materials for low-cost and high-efficiency solar cells. Although perovskite cells are configured similar to the classical solar c…
